[Abstract]  The Min system determines the cell division plane of bacteria. As a cue of spatiotemporal regulation, the Min system uses wave propagation of MinD protein (Min wave). Therefore, the reconstitution of the Min wave in cell-sized closed space will lead to the creation of artificial cells capable of cell division. The Min waves emerge via coupling between the reactions among MinD, MinE, and ATP and the differences in diffusion rate on the cell membrane and in the cytoplasm. Because Min waves appear only under the balanced condition of the reaction-diffusion coupling, special attentions are needed towards several technical points for the reconstitution of Min waves in artificial cells. This protocol describes a technical method for stably generating Min waves in artificial cells. [摘要]  [摘要 ] Min系统确定细菌的细胞分裂平面。作为时空调节的提示,Min系统使用MinD 蛋白的波传播(Min wave)。因此,Min波在细胞大小的封闭空间中的重构将导致能够分裂细胞的人造细胞的产生。闵波出现经由耦合之间反应小号中MinD的,的MinE ,和ATP 和所述differenc ES 在细胞膜上的扩散速度和在细胞质中。因为最小波仅在反应扩散耦合的平衡条件下出现, 特别关注,需要对几个技术要点为闽波在人造细胞重建。该协议描述了一种在人造细胞中稳定产生Min波的技术方法。

[背景 ] 敏系统,它决定了细胞分ER 对称细胞分裂,是在细菌细胞内的组织系统的最显着的例子之一(Rothfield 等人,2005;和罗利特马戈林,2013年)。敏系统使用图案形成在细胞内的时间依赖性蛋白梯度的公知的作为敏波(宽松等人,2008; Halatek和Frey,2012;邦尼等人,2013; Zieske 。等人,2016 ; Kohyama 。等人, 2019 )。Min波是由两种蛋白MinD 和MinE 的反应扩散耦合产生的。通过与ATP结合,MinD 形成二聚体并附着在膜上。的MinE 被招募到的ATP MinD的和诱导ATP酶的活性MinD的。通过MinE ,ATP- MinD 变为ADP- MinD ,并从膜上脱离。ADP- MinD的被转换回ATP- ...

Phos-tag Immunoblot Analysis for Detecting IRF5 Phosphorylation

[Abstract]  While the activation of the transcription factor interferon regulatory factor 5 (IRF5) is critical for the induction of innate immune responses, it also contributes to the pathogenesis of the autoimmune disease systemic lupus erythematosus (SLE). IRF5 phosphorylation is a hallmark of its activation in the Toll-like receptor (TLR) pathway, where active IRF5 induces type I interferon and proinflammatory cytokine genes. By using the phosphate-binding molecule Phos-tag, without either radioisotopes or phospho-specific antibodies, the protocol described here enables detection of the phosphorylation of both human and murine IRF5, as well as that of other proteins. [摘要]  虽然转录因子干扰素调节因子5(IRF5)的激活对于诱导先天免疫应答至关重要,但也有助于自身免疫疾病系统性红斑狼疮(SLE)的发病机制。 IRF5磷酸化是其在Toll样受体(TLR)途径中的活化的标志,其中活性IRF5诱导I型干扰素和促炎细胞因子基因。通过使用不含放射性同位素或磷酸特异性抗体的磷酸结合分子磷酸标签,本文所述的方案可以检测人和鼠IRF5以及其他蛋白质的磷酸化。

背景 在TLR-MyD88途径中,IRF5通过翻译后修饰如泛素化和磷酸化被激活,然后活性IRF5转位到细胞核中并诱导其靶基因(Takaoka等人,2005; Balkhi ,2008; Tamura等人,2008; Hayden and Ghosh,2014)。关于IRF5在SLE中的激活状态,已经报道了IRF5积累在SLE患者的单核细胞核中(Stone等人,2012)。此外,我们最近在SLE鼠模型中显示,IRF5超激活(例如,升高的磷酸化)导致SLE样疾病的发展(Ban 等人,,2016年)。因此,分析IRF5的激活状态对于研究SLE以及先天免疫应答是重要的。磷酸化是IRF5激活的核心,因为许多研究已经通过定点诱变和/或质谱法揭示了IRF5的功能性磷酸化位点(Barnes等人,2002; Lin et al。等人,2005; ...
